  • Multiprocessing interrupt arrangement
    Patent number: 4604500
    Abstract: There is disclosed an interrupt arrangement for use in a multiprocessing system where it is desired to specifically direct interrupts from one processor to any other processor. The arrangement treats the interrupt signal as a data communication between processors. In this regard, common address space is set aside, on a system basis, for interrupt signals. A sending processor first contends for the system bus and then addresses a message to a specific target processor. The message is received at the target processor over the regular communication channel and stored in a FIFO memory. Interrupt messages filter through the memory in order of arrival and cause interrupts to occur at the target processor. The information at the output of the FIFO memory controls the processing of the interrupt.

  • Position coded pulse train
    Patent number: 4748446
    Abstract: Pulse position coding is used to transmit several channels of data from a ground radar transmitter to a receiver in an airborne, remotely-piloted vehicle. The system is designed to ignore interfering pulses, especially those which are synchronized with the transmitter's PRF, by combining a number of noise reduction devices. These include the redundant transmission of address and channel information, the transmission of true and complemented data, the tracking of channels transmitted in a predetermined order, developing an interference count to recognize synchronous pulses, comparing data received for a given channel with data subsequently received for that channel, the use of windows around the expected positions of pulses, and the use of parity. There is also a novel programming arrangement which enables several programs to be stored in a reduced amount of memory space.

  • Non-coherent transmission and equalization in doubly-selective MIMO channels
    Patent number: 9088447
    Abstract: A method and system realize reliable wireless communications in non-coherent multiple-input multiple-output (MIMO) doubly-selective channels. The method uses Grassmannian space-time-frequency block codes and an iterative generalized likelihood ratio test (GLRT) with a multi-dimensional basis expansion model (BEM), decision reordering, and a fixed number of surviving candidates. The computational complexity of a non-coherent MIMO equalizer becomes linear as a function of a code length and a size of a modulation alphabet. The codebook, the alphabet size, the bit labeling, and the block power are optimized using worst-case channel statistics or instantaneous channel states. The method can use soft-information feedback from error correction codes, such as low-density-parity-check codes to improve performance.

  • Joint scheduling and grouping for SDMA systems
    Patent number: 7852802
    Abstract: A joint scheduling and grouping technique provides uplink throughput maximization for space-division multiple access (SDMA) systems under proportional fairness constraints. In a slow-fading narrowband MIMO multiple access channel (MAC) multiple users, each equipped with multiple transmit antennas, communicate to a receiver equipped with multiple receive antennas. The users are unaware of the channel state information (CSI) whereas the receiver has perfect CSI and employs a successive group decoder (SGD). For an open-loop system, an optimum successive group decoder (OSGD) simultaneously minimizes the common outage probability and the individual outage probability of each user, over all SGDs of permissible decoding complexity. For each channel realization, the OSGD maximizes the error exponent of the decodable set of users. An adaptive SGD retains the outage optimality of the OSGD and minimizes decoding complexity. The SGD yields symmetric capacity gains commensurate with the decoding complexity allowed.

  • Distributed switching system having multiple time slot interchanger nodes
    Patent number: 4530092
    Abstract: Communications between stations served by different time slot interchangers (TSI) nodes in a telecommunications network are made possible without the use of either an intermediate stage of time multiplex space division switching or central time slot allocation by an arrangement in which each TSI node is linked to every other node by a patent in which each nodes time slots are "broadcast" to every other node in the network. Each time slot word includes a data or address (D/A) field and a status (ST) field. The D/A field of the time slot word is made subject to interpretation by the contents of the ST field and indicates an encoded item of telecommunications information only when the ST field is "busy". When the ST field requests or acknowledges allocation of the time slot by a TSI, the D/A field respectively identifies the address of the target or requesting TSI.

  • Object-based video processing using forward-tracking 2-D mesh layers
    Patent number: 5936671
    Abstract: The invented method involves the object-based processing of parts of video frames referred to as Video Object Planes using 2-D meshes, wherein the color and shape information associated with the Video Object Planes are assumed to be known at every frame and wherein each video object is processed independently. The invented method more particularly involves utilization of the Alpha Planes, which contain the shape information, in object-based design of an initial 2-D mesh, wherein an Alpha Plane is used to form a constraining polygonal mesh boundary, as well as in object-based tracking of mesh node points, wherein motion vectors of nodes on the mesh boundary are constrained so that these node points always lie along the Alpha Plane boundary, by means of restriction of the search space or back-projection, and mesh-based Video Object Plane mapping takes into account any differences between the mesh boundary and the Video Object Plane boundary.

    Abstract: A process to make/seat a permanent crown in only one patient visit, without the need for a temporary crown, after a digital scan or other impression has been taken prior during a dental cleaning appointment or status check up. The dental information is filed and can be used whenever the patient needs a dental restoration to be made. The impression information will have previously been forwarded to a dental laboratory where a shell-crown can be made that is a perfect match to the outer contour of the existing tooth. Needed improvements/corrections can be made with the use of digital software. Also the margins can be determined and corrected, even in the inter-proximal spaces. Now the laboratory is able to manufacture and provide a finished shell-crown in time for the following doctor appointment of this patient.

  • CONTRASTIVE LEARNING OF UTILITY POLE REPRESENTATIONS FROM DISTRIBUTED ACOUSTIC SENSING SIGNALS
    Publication number: 20220381607
    Abstract: A testing procedure including a data collection procedure and a contrastive learning-based approach, for establishing a profile for utility poles surveyed in an embedding space. Unique properties of utility poles are preserved in a low-dimensional feature vector. Similarities between pairs of samples collected at the same or different poles is reflected by the Euclidean distance between the pole embeddings. During data collection—variabilities of excitation signals are manually introduced, e.g. impact strength, impact locations, impact time ambiguity, data collecting location ambiguity on a DFOS/DAS optical sensor fiber/cable. Data so collected provides a learned model learned complete information about a utility pole and is more robust with respect to uncontrollable factors during operation. A model training procedure that effectively extracts a utility pole intrinsic properties (e.g., structure integrity, dimensions, structure variety) and remote extrinsic influence (e.g.
